Abstract Of The Invention A non-returnable newsprint carrier system is pro-vided which is adapted for winding of newsprint, shipping and storing of newsprint and mounting in reels of offset printing presses on stub shafts, and which is characterized by eliminating the need for a return to the newsprint manu-facturer, increasing core crush resistance during shipping and storing, and reducing roll vibration during unwinding in the printing press. The system comprises a tubular core without metal end caps thereon and defining inside surfaces at opposite ends for receiving therewithin the reel stub shafts of the offset printing press. Core plugs are pro-vided for being inserted into the ends of the tubular core to prevent damage to the and portions of the tubular core and to the newsprint roll. Each of the core plugs comprise a solid body without holes or grooves therein and formed of crush resistant material. The inside surfaces of the oppo-site end portions of the tubular core and the outside sur-faces of the core plugs have substantially the same non-cylindrical configuration, profile and dimensions as the portion of the outside surfaces of the reel stub shafts so that the tubular core will have a full profile fit in surface-to-surface contact over substantially the entire surface area of the reel stub shafts and the core plugs.
the core plugs have an outside lip area for suitable engage-ment or gripping to remove the core plugs from the tubular core.

Description
~3~23~0 A NON-RET~RNABLE NEWSPRINT CARRIER SYSTEM
Fleld Of The Invention This inventlon relates to a non-returnable newsprint carrier system adapted for winding of newsprint, shipping and storing of newsprint and mounting in reels of offset printiny presses on stub shafts having a predetermlned outside configuration and profile for unwinding of ; newsprint. The non-returnable newsprint carrier system is characterized by eliminating the need for return to the newsprint manufacturer, increasing core crush resistance during shipping and storing, and reducing roll vib~atlon during unwinding in the printing press.
Background Of The Invention For the unwinding of newsprint from reels in printing presses, such as the widely used Goss Headliner Offset Printing Press, newsprint has been traditionally wound at the newsprint paper manufacturer onto elongate tubular cores to form rolls of newsprint. These newsprint rolls are often stored at the newsprint manufacturer, then shipped to the newspaper printer, often stored at the newspaper prlnter, and then mounted on stub shafts or chucks in reels of printlng presses to be unwound and fed through the printing presses during the printing of newspapers.
The elongate tubular cores in early times were manufactured of wood and in later times have been manufac-tured of paper having a multi-ply spirally-wound construc-tion. Metal end caps having a longltudinal groove therein have long been utilized on opposite end portions of the core, since early printlng presses were axially driven and :, .

~3223~0 braked. The metal end caps reinforced the core ends to transmlt axial torque and roll weight to the narrow shoulders of the outside surfaces of the printing press reel stub shafts or chucks. The metal end caps were also thought to reinforce the opposite end portlons of the core against damage to the end portions of the core and the newsprint roll during storage and shlpment.
Later printing presses became peripherally drlv~n and braked and the demand for axial torque diminished;
however, the requirement for weight support at the point of contact of these metal end caps with the narrow shoulders of the stub shafts or chucks of the printing press reels increased over the years due to lncreased newsprlnt roll weights and increased newsprlnt unwinding speeds. The result of such increased newsprint roll welghts and unwinding speeds was less effectlve control of the core in bouncing or vibrating on the reel stub shafts or chucks and thus causing undeslrable vibration in the newsprint being unwound and fed into the printing presses.
The usual industry response to this problem, rather than redesign of the newsprint core, has heretofore been to build more sophisticated newsprint roll chucks or stub shafts lncludlng web vibration controls, such as air pressure chucks or stub shafts which increasingly "home in" on expiring rolls as the cores retract from the stub shafts or chucks due to deflection and vibration.
This type of newsprint cores having metal end caps did not allow for the cores to be non-returnable by the newspaper printers and the newspaper printers were requested to return all of these cores to the paper manufacturers for reuse in winding additional rolls of newsprint. This , , .;. . .
, ~ , ~ .; , . ., .
~23~(3 created handllng problems both with the newspaper printer and with the paper manufacturer.
In recent times, there has been some attempt to provide non-returnable newsprint cores by ellmlnatlng the metal end caps on the cores. However, no slgniflcant rede-sign of the core constructlon was effected after removal of the metal end caps, other than to burnish or grind away a small flat portion at the opposite ends of the paper cores to provlde for a contact area for the cores on the narrow shoulders of the outside surfaces o the prlnting press reel stub shafts or chucks, generally along the lines previously provided by the metal end caps. Due to the increased welght and unwinding speeds of the newsprlnt rolls, elimlna tlon of the metal end caps with thls type of core was not found to be satisfactory by most newspaper printers and, thus, attempts at non-returnable newsprint cores have largely been unsuccessful.
As newsprint roll weights increased, damage to the end portlons of the tubular core and the newsprint roll durlng shipplng and storage increased. This often occurred ~ ~ ~
as a result of lmpact on the outslde circumference of the newsprint roll, partlcularly at the ends thereof. The result was that distortlon to the metal end caps was dupli-cated on the inside surface thereof and the metal end caps could not rlde up far enough on the shoulder of the prlnting press reel stub shafts and would consequently bounce and vibrate as the newsprlnt roll is unwound ln the prlntlng press.

storage to prevent damage to the end portions of the tubular core and to the newsprin-t roll. These core plugs were removed prior to mounting of the newsprint roll in the reels of the printing presses. Such core plugs were formed of a variety of types of materials, such as wood, plastic or other crush-resistant material. The most common core plugs utilized were generally cylindrical in shape and utilized a centrally located hole therethrough for the insertion of a tool therein to remove the core plug from the core after storage and shipping.
It was found that this centrally located hole for re~oval of the core plug from the core resulted in a weakened core plug which did not provide all of the core crush resis-tance desired. More recently, improvements to thls construction of a core plug have been suggested, such as disclosed in U.S. Patent ~,484,715, wherein the core plug lncludes an openlng or grooves spaced from the center of thereof and near its remote outer edge for use in removal of the core plug from the core, while increasing crush resistance of the core plug. However, it has been found that this core plug constructlon with a groove at its outer edge, rather than a centrally located hole, may not provide sufficient core crush resistance ln some instances~
Ob~ects And Summary Of The Invention It is, therefore, the ob~ect of this invention to provide a non~returnable newsprint carrler system adapted for wlnding of newsprint, shipping and storing of newsprlnt and mounting in reels of offset printlng presses on stub shafts having a predetermined non-cylindrical outside con-figuratlon and profile for unwinding of newsprint, and which -: ~ ", ~22~0 solves the above discussed problems in prior systems by eliminating the need for return of the core to the newsprint manufacturer, increasing core crush resistance cluring shipping and storing, and reducing roll vibration during unwinding in the printing press. -It has been found by this invention that the above object may be accomplished by providing a non-returnable newsprint carrier system including generally the following: a non-returnable newsprint carrier system adapted for winding of newsprint, shipping and storing of newsprint and mounting in reels of offset printing presses on stub shafts having a predetermined non-cylindrical outside surface configuration and profile for unwinding of newsprint, and characterized by eliminating the need for return to the newsprint manufacturer, increasing core crush resistance during shipping and storing, and reducing roll vibration during unwinding in the printing press; said system comprising an elongate tubular core of predetermined dimensions for winding of newsprint thereon to form a roll of newspr.int and having opposite end portions without metal end caps thereon and defining inside surfaces for receiving therewithin the reel stub shafts to mount the roll of newsprint in the offset printing press, said inside surfaces of said opposite end portions of said tubular core having predetermined non-cylindrical configuration, profile and dimensions for being adapted to be mounted on complimentary portions of the outside surfaces of the reel stub shafts of the offset printing press so that said tubular core will be adapted to have a full profile fit in surface-to-surface contact over substantially the entire surface area of the reel stub shafts received within said core, said non-cylindrical configuration comprising means for reducing roll ~:
vibration during unwinding of the newsprint in the offset printing press; and core plugs for being inserted into the endportions of said tuhular core after winding of the newsprint roll and during shipping and storage to prevent damage to the end portions of said tubular core and to the newsprint roll, each of said core plugs comprising a solid body without holes 13223~0 - 5a -or grooves therein, having a generally circular cross~
sectional configuration, being formed of wood, plastic or the like crush-resistant material, and having an outside surface area of substantially the same non cylindrical configuration, profile and dimensions as the outside surface of the reel stub shafts of the offset printing press and saicl inside surfaces of said opposite end portions of said tubular core for being positioned therewithin and a circumferencial lip area at the end of said core plug for being positioned at the end of said tubular core for suitable engagement or gripping to remove said core plugs from said tubular core.
According to preferred aspects of the invention, an elongate tubular core, preferably paper, of predetermined dimensions is provided for winding of newsprint thereon to form a roll of newsprint and which has opposite end portions without metal caps thereon for receiving therewithin on inside surfaces thereof the reel stub shafts to mount the roll of newsprint in the offset printing press. The inside surfaces of the opposite end portions of the tubular core have substantially the same non-cylindrical configuration, profile and dimensions as the outside surfaces of the reel stub shafts of the offset printing press so that the tubular core and the newsprint roll will have a full profile fit in surface-to~
sur~ace contact over substantially the entire surface area of the reel stub shafts received within the core, rather than only at the shoulder portion of the reel stub shafts as was previously the practice with metal end caps, to reduce roll vibration during unwinding of the newsprint in the offset printing press. Also, the ends of a paper core without metal end caps will by its structure absorb impact on its outside circumference without transmitting the distortion to the inside profile so that the core will still spin dynamically on the printing press reel stub shafts without vibration.

Core plugs are provided for being inserted into the end portions of the tubular core after winding of the newsprint roll and during shipping and storage to prevent damage to the end portlons of the tubular core and to the newsprint roll. Each of the core plugs comprises a solid body without holes or grooves therein, having a generally circular cross-sectional configuration, being formed of wood, plastic or the like crush resistant material. Each of the core plugs has an outside surface area of substantially the same non-cylindrical configuration, profile and dimen-sions as the outside surface of the reel stub shafts of the offset printlng press and the inside surfaces of the oppo-site end portions of the tubular core for being positioned therewithin. Each of the core plugs further includes a cir-cumferential lip area at the end of the core plug for belngpositioned at the end of the tubular core for sultable enga-gement or gripping to remove the core plu~s from the tubular core.
Thus, the newprint carrier system of thls invention has been deslgned to be non-returnable by eliminating the previously utillzed metal end caps which were generally con-sidered necessary in the industry. The inside surfaces of the opposite end portlons of the core and the outside sur-face of the core plug have been deslgned to have substan-tially the same dimensions, conflguration and profile as theportion of the stub shafts or chucks of the reels of the off set printing presses which are received withln the opposite end portions of the newsprint roll core. This constructlon provides a full profile fit in surface-to-surface contact 30 over substantially the entire surface area of the reel '!
stub shafts received within the core and the lnside surfaces ' ''~;,. ..

of the opposite end portions of the core to reduce by vibra-tlon during unwindlng of the newsprint ln the offset prlnting press and to provide additional support allowing the ellmination of the metal end caps. The core plugs have also ellmlnated the undesirable holes or grooves heretofore utilized therein for removal thereof from the opposite end portions of the newsprint roll core to increase core crush r0sistence. The core plugs provide a l:lp on the outside ends for suitable engagement or gripping by a tool or th~
like to remove the core plugs from the newsprint roll core.
Therefore, for the first time, a non-returnable newsprint carrier system has been designed which is specifl-cally adapted to flt the non-cylindrical profile and con-flguration of the stub shafts or creels of the printing presses without the need for any modificatlons to the prlnting presses to eliminate all of the problems previously encountered with such systems.

According to preferred aspects of the invention, an elongate tubular core, preferably paper, of predetermined dimensions is provided for winding of newsprint thereon to form a roll of newsprint and which has opposite end portions without metal caps thereon for receiving therewithin on inside surfaces thereof the reel stub shafts to mount the roll of newsprint in the offset printing press. The inside surfaces of the opposite end portions of the tubular core have substantially the same non-cylindrical configuration, profile and dimensions as the outside surfaces of the reel stub shafts of the offset printing press so that the tubular core and the newsprint roll will have a full profile fit in surface-to~
sur~ace contact over substantially the entire surface area of the reel stub shafts received within the core, rather than only at the shoulder portion of the reel stub shafts as was previously the practice with metal end caps, to reduce roll vibration during unwinding of the newsprint in the offset printing press. Also, the ends of a paper core without metal end caps will by its structure absorb impact on its outside circumference without transmitting the distortion to the inside profile so that the core will still spin dynamically on the printing press reel stub shafts without vibration.

Core plugs are provided for being inserted into the end portions of the tubular core after winding of the newsprint roll and during shipping and storage to prevent damage to the end portlons of the tubular core and to the newsprint roll. Each of the core plugs comprises a solid body without holes or grooves therein, having a generally circular cross-sectional configuration, being formed of wood, plastic or the like crush resistant material. Each of the core plugs has an outside surface area of substantially the same non-cylindrical configuration, profile and dimen-sions as the outside surface of the reel stub shafts of the offset printlng press and the inside surfaces of the oppo-site end portions of the tubular core for being positioned therewithin. Each of the core plugs further includes a cir-cumferential lip area at the end of the core plug for belngpositioned at the end of the tubular core for sultable enga-gement or gripping to remove the core plu~s from the tubular core.
Thus, the newprint carrier system of thls invention has been deslgned to be non-returnable by eliminating the previously utillzed metal end caps which were generally con-sidered necessary in the industry. The inside surfaces of the opposite end portlons of the core and the outside sur-face of the core plug have been deslgned to have substan-tially the same dimensions, conflguration and profile as theportion of the stub shafts or chucks of the reels of the off set printing presses which are received withln the opposite end portions of the newsprint roll core. This constructlon provides a full profile fit in surface-to-surface contact 30 over substantially the entire surface area of the reel '!
stub shafts received within the core and the lnside surfaces ' ''~;,. ..

of the opposite end portions of the core to reduce by vibra-tlon during unwindlng of the newsprint ln the offset prlnting press and to provide additional support allowing the ellmination of the metal end caps. The core plugs have also ellmlnated the undesirable holes or grooves heretofore utilized therein for removal thereof from the opposite end portions of the newsprint roll core to increase core crush r0sistence. The core plugs provide a l:lp on the outside ends for suitable engagement or gripping by a tool or th~
like to remove the core plugs from the newsprint roll core.
Therefore, for the first time, a non-returnable newsprint carrier system has been designed which is specifl-cally adapted to flt the non-cylindrical profile and con-flguration of the stub shafts or creels of the printing presses without the need for any modificatlons to the prlnting presses to eliminate all of the problems previously encountered with such systems.
